• Running has sharply diminishing returns — about 30 minutes a week captures most of the longevity benefit. Beyond that, you’re not gaining much.
• Walking is the standout: 12,000 steps/day is associated with a ~75% reduction in all-cause mortality. Running 10,000 steps doesn’t come close to walking 10,000 steps.
• There’s four-pillars of exercise for longevity: aerobic, HIIT, strength training, walking. Total required time: about 60–90 minutes/week for the structured exercise.
• Sleep’s longevity data is weaker than most people assume — it didn’t make the top tier of habits when ranked by mortality reduction.
• Biological age clocks are evolving fast (PhenoAge → BortzAge), but I don’t find them useful for choosing habits compared with all-cause mortality studies.

Running might not be the "ideal" exercise, but it is still very good, as compared to being sedentary. For people who enjoy running, might as well do it.

Don't know about running (largely on your forefoot), but when I see people jogging I can't help but notice how violently their pelvis & lower back shifts back & forth as their feet hit the ground largely flat footed.  I also wonder what that kind of jarring might be doing to the brain and internal organs, particularly during distance runs.  

 

If you're truly into aerobics, methinks swimming would be the ultimate exercise, and infinitely less jarring to the brain & bodkin.  Speed-walking might also be a kinder aerobic if you don't have easy access to a pool or body of water.

Swimming is the best, I would think, for aerobic exercise, however (there is always a however), if you are swimming in chlorinated water all the time, that might not be good long term - although I am unsure of any studies comparing swimmers to the general population.
